Warranty. Mitsubishi Electric AE2000-SWA, AE4000-SW, Low-Voltage Air Circuit Breakers series Type AE-SW, AE3200-SW, AE630-SW

1. Standard operation environment

The standard operation environment is an environment where all of the following conditions are met. Unless otherwise specified, use the AE Series air circuit breaker in the following environment.

① Standard ambient temperature

Use in the range of +40 °C max. and -5 °C min. However, the average temperature over 24 hours must not exceed

+35 °C.

② Altitude: 2000 m (6600 feet) or less.

③ Environmental conditions

The air must be clean with the max. temperature of

+40 °C and the relative humidity of 85% or less, and without condensation.

Do not use and store in an atmosphere with corrosive gas, such as sulfide gas and ammonia gas.

(H 2 S 0.01 ppm or less, SO 2 0.05 ppm or less, NH 3 0.25 ppm or less)

④ Installation condition

Install the AE Series air circuit breaker in accordance with the instructions on the catalog and the instruction manual.

⑤ Guideline for replacement

Expected product life is 15 years in the standard operation environment.

Time of replacement is highly influenced by the operation environment. Refer to the inspection and maintenance section of this instruction manual.

Warranty

If any faults or defects (hereinafter “Failure”) found to be the responsibility of Mitsubishi Electric occurs during use of the product within the warranty period, the product shall be repaired at no cost via the sales representative or Mitsubishi

Electric Sales office. However, if repairs are required onsite at domestic or overseas locations, expenses to send an engineer will be charged.

1. Warranty period

The warranty period of the product shall be for twelve

(12) months after the date of purchase or delivery to the designated place. Note that after manufacture and shipment from Mitsubishi Electric, the maximum distribution period shall be six (6) months, and the longest warranty period after manufacturing shall be eighteen (18) months. The warranty period of the repaired parts shall not exceed the warranty period of the original product before repairs.

2. Warranty coverage

(1) The primary failure diagnosis should be performed by users. However, if required by users, Mitsubishi

Electric or Mitsubishi Electric Sales office may be able to perform the diagnosis. In that case, for damages caused by any cause found to be the responsibility of

Mitsubishi Electric, the diagnosis will be performed at no cost. For details, contact a distributor.

(2) The coverage shall be limited to ordinary use within the usage state, usage methods, usage environment, and other conditions which follow the instructions and precautions given in the instruction manual, user’s manual, and caution labels on the product.

(3) Even within the warranty period, repair cost shall be charged for the following cases.

[1] Failure occurring from inappropriate storage or handling, carelessness or negligence by the user.

Failure caused by selection of hardware or software design on the user side.

2. Special operation environment

When the product is used in a condition other than the standard operation environment, its service life may be shorter.

① Special operation environment

Operation with high temperature and high humidity.

Operation in an environment where corrosive gas is present.

② Special ambient temperature

When the ambient temperature exceeds +40 °C,

“uninterrupted current” is reduced.

③ Special altitude

When using the product at an altitude over 2000 m, heat dissipation becomes less. This leads to a reduction of the operation voltage, current capacity, and breaking capacity. The dielectric strength is also lowered by the air pressure. Please contact us for details.

[2] Failure caused by modifications, etc. to the product by the user without any approvals from Mitsubishi

Electric.

[3] In case Mitsubishi Electric product is assembled into a user’s device, failure that could have been avoided if functions or structures, judged as necessary in the legal safety measures the user’s device is subject to or as necessary by industry standards, had been provided.

[4] Failure that could have been avoided if the maintenance described in the user’s manual has been performed.

[5] Failure caused by external irresistible forces such as fires or abnormal voltages, and failure caused by natural disasters such as earthquakes, lightning, wind and water damages.

[6] Failure caused by reasons unpredictable based on scientific technology standards at the time of shipment from Mitsubishi Electric.

[7] Any other failure found not to be the responsibility of Mitsubishi Electric or that admitted not to be so by the user.

In addition, the warranty applies only to the product delivered. It does not apply to the damage that is caused by the failure of the product.
